Claims (4)
1. Gewindeformende Schraube (1) zum direkten Einschrauben
in eine Bohrung, die in Beton, Mauerwerk oder
dergleichen Werkstoff eingebracht ist, wobei die
Schraube (1) einen Schraubenkopf (2) mit einem
Werkzeugangriff, einen im wesentlichen zylindrischen
Schaft und vorzugsweise eine kegelstumpfartig oder
pyramidenstumpfartig verjüngte Spitze (3) aufweist,
ferner der Schaft mindestens von der Spitze bis über
einen wesentlichen Teil seiner Länge Gewinde aufweist,
wobei das Verhältnis von Außendurchmesser (DA) zu
Kerndurchmesser (DK) der Schraube etwa 1,25 bis 1,5

Außendurchmesser (DA) zu Steigung (P) des Gewindes etwa
1,25 bis 1,40 beträgt, der Flankenwinkel (α) des
Gewindes etwa 55° bis 60° beträgt und daß parallel zu
dem Gewindegang (4) ein zweiter Gewindegang (5)
ausgebildet ist, der nur geringfügig über den Kern
vorsteht und erheblich gegenüber dem ersten Gewindegang
(4) zurücksteht.
2. Schraube nach Anspruch 1, dadurch gekennzeichnet, daß
der Flankenwinkel des zweiten Gewindeganges (5) dem des
ersten Gewindeganges (4) gleicht.
3. Schraube nach Anspruch 1 oder 2, dadurch
gekennzeichnet, daß der zweite Gewindegang (5) nur um
etwa 2 bis 4 Zehntel Millimeter über den Kern vorragt.
4. Schraube nach einem der Ansprüche 1 bis 3, dadurch
gekennzeichnet, daß am spitzenseitigen Anfang des ersten
und/oder zweiten Gewindeganges (4, 5) über wenigstens
